High-density Polyethylene Piping Products

Spirolite®: Easier to Handle. Faster to Install. Large-Diameter HDPE Pipe that Delivers.

Spirolite is a superior HDPE pipe system for stormwater, sewer, tanks, and relining—lightweight, easy to install, and built for 100+ years of service. It outperforms RCP, FRP, and steel in lifespan, installation efficiency, and overall cost-effectiveness.

A structured, high-density polyethylene (HDPE) pipe system, Spirolite is designed for fluid conveyance in gravity and low-pressure applications. Spirolite is ideal for stormwater, sewer, culvert relining, and custom-fabricated structures—including tanks, manholes, wet wells, and lift stations—made from spirally wound HDPE and available in diameters up to 120 inches or larger. With bell and spigot or welded joint options, it delivers long-term durability, corrosion resistance, and installation advantages that outperform traditional materials like concrete, steel, and fiberglass.

Why choose Spirolite?

fpo

fpo

Up to 75% lighter than concrete or steel, Spirolite’s unit weight is considerably less than traditional pipe products for municipal and industrial applications, significantly reducing installation costs and equipment needs.

fpo

Outlasts traditional materials with minimal maintenance.

fpo

Spirolite’s high resistance to chemicals, corrosion and abrasive materials offers more reliable long-term performance in a wide array of applications.

fpo

With high elongation at break and high stress-crack resistance, Spirolite handles ground movement (settling) and seismic shifts (such as from an earthquake) better than rigid materials.

fpo

Available up to 120-inch diameters, competing with RCP, FRP, and steel for big projects.

fpo

Spirolite’s bell and spigot joint meets ASTM D3212 criteria to deliver leak-free performance in sanitary sewer, industrial waste and other critical applications.

Beyond Concrete: The Advantages of HDPE Pipe in Modern Piping Solutions

In a world where comfort often breeds resistance to change, the emergence of high-density polyethylene (HDPE) in large-diameter piping systems is revolutionizing the industry. While reinforced concrete pipes (RCPs) have long been the norm, HDPE offers a plethora of benefits from installation to long-term performance. Let’s delve into why HDPE is becoming the preferred choice over RCP.
